BARBER SHEARS.

Application filed March 19, 1926.

The present invention relates to barber shears and aims to provide astructure which is an improvement over the ordinary barber shears, inthat it can always be maintained sharp, may be adjusted to its properset and wherein the worn parts can be replaced.

Another important object of the invention is to provide shears of thisnature which are simple in construction, efficient and reliable in use,and operation, easy to adjust and manipulate, and otherwise well adaptedto the purpose for which they are designed.

Vv ith the above and numerous other objects in view as will appear asthe description proceeds, the invention resides in certain novelfeatures of construction, and in the combination and arrangement ofparts as will be hereinafter more fully described and claimed.

In the drawing:

Figure 1 is an elevation of a pair ofshears embodying the features of myinvention,

Fig. 2 is a transverse section throughthe blades in a closed position,

Fig. 3 is a. transverse section through the pivoted portions of theblades,

Fig. 4 is a fragmentary longitudinal section through one of the blades,

Fig. 5 is a perspective View of a portion of one of the blades,

Fig. 6 is a perspective view of the wire spring, and

Fig. 7 is a perspective view of one of the detachable cutting portions.

Referring to the drawing in detail, it will be seen that the numerals 5designate two blades having the handle portions 6 and tinengagingterminals or rings 7, one of which is provided with an abutment screw 8and the other with an extension 9. The abutment screw 8 may be adjustedto limit the approach of the portions or terminals 7 toward each other,and therefore limit the approach of the ends of the blades 5 toward eachother.

The blades are pivoted together by a bolt 10 threaded in one blade and aplug 11 threaded in the other blade and having a recess 12 for receivingthe head of the bolt 10. By the adjustment of the plug 11 or the bolt 10or the both of them, the blades may be adjusted to normally create moreor less friction therebetween. However, in order to prevent thisfriction, I provide a set screw 30 through one blade bearing against arounded portion 31 on the other blade.

Serial No. 95,982.

This set screw and rounded portion prevent any binding effect. The setscrew may be adjusted to rub on the portion 31' and tends to pry on theend of the shears and alternate ly throws the two cutting portionstogether, thereby producing the desired friction only on the cuttingportion. If in the manufac ture of these cutting portions, a pairhappens to be a little thick, the plug 11 may be turned to adjust theblades apart to accommodate the thickness of the cutting portions.

The plug also maintains the shears steady,

that is, prevents wobbling, and when it is worn, can be replaced. Eachblade 5 has a recess 13 formed there- 1n and extending longitudinallythereof adj acent the cutting edge thereof, starting from the point orterminal to a point adjacent the pivot. The bottom of the recess isbeveled and ridged as is indicated at 15. A lug 16 extends inwardly overthe upper portion of the recess. A cutting portion 17 is receivable inthe recess 13, being shaped to fit snugly therein and having a notch atone end as at 18 to receive the lug 16, and an opening 19 adjacent theother end entering a pocket 20. A spring wire 21 at one end is hooked asat 22 to extend through a slot 23 in the blade and the opening 19 in thecutting portion 17 terminating within the pocket 20.

The other end of the spring wire is bent and engaged in a screw 24threadedly mounted in the blade. By turning the screw 24., the springmay be tensioned as desired for holding the cutting edge portion in theblade.

It is thought that the construction, operation, utility, and advantagesof this inven tion will now be clearly understood without a moredetailed description. The present embodiment of the invention has beendisclosed in detail, since in actual practice it attains the features ofadvantage enumerated as desirable in the statement of the invention andthe above description. It will be apparent.

Having thus described myinvent-ion, what i I claim as new is 1. A deviceof the class described including a pair of blades, means for pivotingthe blades together, each blade being provided with a longitudinallyextending recess start- NEC ing at the extremity thereof and terminatinga slight "distance froin the pivot thereof, a. lug projecting from theend of the recess inwardly thereof adjacent thepivot, a cutting edgeportion having a notch at one end, said cutting edge portion adapted tobe. received in the recess and the lug adapted to extend in the notch,and a spring engaged with the other end of the cutting edge porti'on andwith the blade.

2 A device of the class described including a pair ofhlades, means forpivotiiigthe blades together, each blade being provided with alongitudinally extending recess starting'at the extremity thereof andterminating a slight distance from the pivot thereof, a lug projectingfrom the end of the recess inwardly thereof adjacent the pivot, acutting edge portion having a notch at one end, said cutting edgeportion adapted'to be received in the recess, and the lug adapted toextend in the notch, a wire spring having one end engaged with the otherend of the cutting edge portion, and a screw threadediy engaged 'in theblade and having the other "end of the spring Wire engaged therewith.

In testimon whereof I aflix my signature.
